This beautifully restored museum is worth a visit for its wide-ranging exhibits on everything from archeology to ethnology to numismatics to colonial weaponry. The museum has a beautiful, bright inner courtyard displaying some lovely, early 19th-century furniture, as well as an ornate horse-drawn hearse. Lots of natural light illuminates the quirky, Victorian-era potpourri of natural-history exhibits, from bugs, butterflies, polymitas (snails with multicolored shells), to preserved fleas in nuptial dress, viewed under a magnifying glass. Antique buttons and buckles, pen nibs, death masks, a Masonic lodge throne in the shape of a peacock. On the historical side, there are the usual photographs of Cárdenas heroes of the wars of independence and the Revolution and a gruesome reminder of the risks rebels took, in the form of the garrote used to strangle victims to death.
